Brocure and Datasheet for Wyse Technology' series 9000i SMP Unix system from 1991.
One of only a few Unix systems produced by Wyse Technology in the late 1980s and early 1990s, this was an impresssive Symmetric Multi-Processor (SMP) design that featured up to 8 Intel 80486 processors and ran a Wyse branded version of the Unix operating system.
A good example of early attempts to evolve the Intel x86 platform from PCs to business computers before the concept of a 'server' became realized.
